The case of the missing fatwa, take 6

The invaluable MEMRI observes:

In President Obama’s announcement of the joint statement following the conclusion of the negotiations in Lausanne, he again mentioned the nonexistent fatwa, stating as fact that Iran’s Supreme Leader has issued a fatwa against the development of nuclear weapons.[1] This assertion by the president is not true. Such a fatwa has never been issued, and to this day no one has been able to show it, as MEMRI has detailed in five reports so far.[2]

The following is the sixth MEMRI report, constituting an update about this nonexistent fatwa.
